graphite mining equipment manufacturer

Mining pioneering methods of transportation: the use of road development, such as Liu Mao Graphite Mine, ore annual output of 244,000 tons, the annual stripping a total of 810 000 t, transport with TATRA815 dump truck load of 15t; South Shu Yue stone mining area, ore annual output of 243,000 tons, the annual stripping total of 828 000 t transport ZG150 and the BJ374 type dump truck load of 15t and 20t.

graphite mining process

Inner and graphite mine, ore annual output of only 120 000 t years stripping a total of 370 000 t, the transport 8t dump truck. Underground mining to open up shipping methods: First, adit development, such as Lu Tong graphite mine; inclined to open up, as a rock Graphite Mine. Small-scale mining as a rock graphite mine ore annual output of only 20,000 tons, inclined to enhance 1.2m hoist roadway transportation artificial cart, tramcar 0.55m3 of dump trucks.

Crystalline graphite ore deposits are prolific in the regional metamorphism - deep metamorphic rocks. Stratiform ore bodies, bedded or lenticular medium-ore hardness, tightness coefficient f = 5 ~ 8 or f = 8 ~ 10. Open-pit mining process and is generally open pit, Liu Mao graphite mine, the villa graphite mine in South Yue quarry road to open up a large open pit face arrangement parallel to the direction and the vertical toward two, perforation KQ-150 DTH rock drill, mining loaded using 1m3, 2m3 electric excavators, face transport vehicles, selection of car models and develop the transport vehicle.

Aphanitic graphite mines are prolific in the contact metamorphic coal-bearing metamorphic shale the orebody layered, stratiform, banded and lenticular ore earthy, soft, friable, creamy. Underground mining, mining methods, Lu Tong graphite ore and rock graphite mine the ore and surrounding rock stability, so are caving mining method.

Lu Tong graphite mine combined with the characteristics of the ore and host rocks, after years of practice, the creative use of pillar tilt sublevel caving, use the creamy nature of the ore in quasi and recovery process, the friction angle is small feature will all roadways are made of inclined ore chute inclination of 42 °, every 7m boring segment access road inclination angle of 18 ° to 20 °, segmented Inclined an inclination of 18 ° ~ 20 °, the recovery into the road inclination 10 ° to 11 °.

Segmented contact the Road segment Inclined and mining approach floor laying enamel chute ore slipped well down the chute from slippery to the ore, the entire recovery process is no longer set other shipping equipment, this method with no end column compared to sublevel caving, simple equipment, loaded freight province, easy to grasp. Nugget production capacity of 36t / d, face ergonomics of 3.35 t / (working class).
